SBIR Phase II: Implementation of Sex Pheromone-Based Systems to Suppress Populations of Soybean Aphids

这个小型企业创新研究（SBIR）二期项目建议开发基于性信息素的技术，用于监测、大规模诱捕和干扰大豆蚜虫的交配。自首次在北美出现以来，新入侵的大豆蚜虫（Aphis glycine Matsumura）由于直接取食损害或蚜虫传播植物病毒而继续造成重大的大豆产量损失。2003年，大豆蚜虫侵害的总面积估计超过800万英亩，在美国三个最大的大豆种植州（伊利诺伊州、爱荷华州和明尼苏达州），产量损失在32% - 45%之间。该项目将研究新的抑制策略来减少这种害虫的种群，从而减少以大豆为食的后续种群的规模。该项目的商业应用将是管理大豆作物中的蚜虫。该研究旨在增加对蚜虫化学生态学的认识，并为如何最有效地利用这些新的蚜虫性信息素控制策略提供新的认识。这将帮助世界上最大的大豆出口国美国的种植者以最小的成本管理大豆蚜虫，提高作物质量和产量，从而提高他们在世界市场上的竞争力。

This Small Business Innovation Research (SBIR) Phase II project proposes to develop sex pheromone-based techniques for monitoring, mass trapping, and mating disruption of the soybean aphid. Since its first appearance in North America, infestations of the newly invasive soybean aphid, Aphis glycines Matsumura, have continued to cause a significant soybean yield loss due to either direct feeding damage or the vectoring of plant viruses by the aphid. In 2003, the total acreage with soybean aphid infestation was estimated at over 8 million, with yield loss ranging from 32% - 45% in the three biggest soybean growing states in the U.S. (Illinois, Iowa and Minnesota). This project will investigate novel suppression strategies to reduce populations of this pest, thereby reducing the size of the subsequent populations feeding on soybeans.The commercial application of this project will be to manage aphids in the soybean crop. The research aims to increase knowledge of the chemical ecology of aphids, as well as provide a new understanding of how to use these novel aphid sex pheromone-based control strategies most effectively. This will help growers in the U.S., the world's largest soybean exporting country, to improve crop quality and yield at a minimal cost for soybean aphid management, thereby increasing their competitiveness in the world market.
